A catalyst composition comprising a complex of catalytic oxides of iron, bismuth, molybdenum, cobalt, cerium, antimony, at least one of nickel or magnesium, and at least one of lithium, sodium, potassium, rubidium, or thallium, and characterized by the following empirical formula:ABCFeBiCoCeSbMoOwherein The catalyst is useful in processes for the ammoxidation of an olefin selected from the group consisting of propylene, isobutylene or mixtures thereof, to acrylonitrile, methacrylonitrile and mixtures thereof, respectively.

Catalyst for the manufacture of acrylonitrile

A process increasing the yield of both HCN and acetonitrile produced during the manufacture of acrylonitrile comprising introducing a hydrocarbon selected from the group consisting of propylene and propane, a crude ketone and/or a mixture of at least two ketones, ammonia and air, into a reaction zone containing an ammoxidation catalyst, reacting the. hydrocarbon, the ketone, ammonia and oxygen over said catalyst at an elevated temperature to produce acrylonitrile, hydrogen cyanide and acetonitrile, and recovering the acrylonitrile, hydrogen cyanide and acetonitrile from the reactor.

Ammoxidation of a mixture of ketones to acetonitrile and HCN

A process for the preparation of a promoted VSbO catalyst comprising mixing a vanadium compound, at least a first portion of an antimony compound, and at least a portion of the support material to form a slurry, heating the slurry to remove the water, calcining the dried slurry to form a catalyst precursor, combining the catalyst precursor with a second aqueous sol containing the remaining portion of the support material and the remaining portion of the antimony compound to form a second slurry, drying the second slurry to remove the water and calcining the dried mixture to form the finished catalyst.

Two-stage preparation of promoted V/Sb-oxide ammoxidation catalysts

A process increasing the yield of both HCN and acetonitrile produced during the manufacture of acrylonitrile comprising introducing a hydrocarbon selected from the group consisting of propylene and propane, a crude ketone and/or a mixture of at least two ketones, ammonia and air, into a reaction zone containing an ammoxidation catalyst, reacting the hydrocarbon, the ketone, ammonia and oxygen over said catalyst at an elevated temperature to produce acrylonitrile, hydrogen cyanide and acetonitrile, and recovering the acrylonitrile, hydrogen cyanide and acetonitrile from the reactor.

Method for the manufacture of acrylic acid

A process for increasing the yield of one or both co-products HCN and acetonitrile produced during the manufacture of acrylonitrile comprising introducing a hydrocarbon selected from the group consisting of propylene and propane, a mixture comprising one or more alcohols selected from crude methanol, crude ethanol or crude propanol, ammonia and air into a reaction zone containing an ammoxidation catalyst, reacting the hydrocarbon, alcohol, ammonia and oxygen over said catalyst at an elevated temperature to produce acrylonitrile, hydrogen cyanide and acetonitrile, and recovering the acrylonitrile, hydrogen cyanide and acetonitrile from the reactor.

Ammoxidation of a mixture of alcohols to a mixture of nitriles to acetonitrile and HCN

A process for regenerating molybdenum containing ammoxidation catalyst comprising replacing the molybdenum loss from the catalyst during the ammoxidation reaction wherein ammonium dimolybdenum is utilized as the source for replacement of the molybdenum loss from the original catalyst.

A catalyst composition comprising a complex of catalytic oxides of iron, bismuth, molybdenum and calcium and characterized by the following empirical formula:

Catalyst for the manufacture of acrylonitrile and hydrogen cyanide

A process for preparing a catalyst having the following formula:

Method of improving the attrition resistance of V/SB oxide based catalyst

A catalyst having the atomic ratios set forth in the empirical formula below:

Ammoxidation catalysts containing germanium to produce high yields of

A process for the manufacture of a Pd/Au/alkali metal catalyst, preferably a fluid bed catalyst used in the production of vinyl acetate comprising impregnating a microspheroidal support with a hydroxy-free metal salt solution of Pd and Au substantially free of barium and halide, reducing said salts to deposit Pd and Au on said support surface and impregnating said support with a halide-free metal salt of an alkali metal (preferably potassium).

Process for the preparation of vinyl acetate catalyst

A process for the substantial or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing methanol into said reactor in the upper portion of the reactor at a location where the methanol reacts with at least a portion if not substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, methanol is introduced into the reactor at below its coking temperature. In particular, when an oxygen lean fluid bed catalyst is utilized, an additional oxygen containing gas is introduced into the reaction at a distance between about 8 to 14 inches from the methanol feed location.

Process for elimination of waste material during manufacture of

A process for the substantial or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing an organic compound(s) into said reactor at a location where the compound(s) reacts with substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, the organic compound is methanol which is introduced into the reactor at below its coking temperature.
